Enthalpy

The A/ENT is an enthalpy controller which is used to measure temperature and humidty before converting them into a sourced relay output.  The supply voltage to the A/ENT is common to both the N/O and N/C contacts of the 10A Form 1C Relay.  Typically used in conjunction with the A/DIFF-ENT, the A/ENT converts a capacitive type humidity sensor into a linear 2-wire, 4 to 2- mA output.  Its signal is proportional to a scale of 0 to 50 BTU's and is geared towards OEMs of economizers and other devices that require an enthalpy input or economizer control.  Each unit in this series features a coated circuit board and jumper selectable elevation settings.  The A/ENT is covered by ACI's Five (5) Year Limited Warranty.
